the rule of thumb is: you dont understand a certain sport, you shut up about it.
i don't know anything about american football, it looks utterly ridiculous and boring to me, but based on my total lack of knowledge i shut up about it.
maybe you should consider a similar course of action, you are after all talking about the most popular sport in the entire world....

uhm, no. next to nothing really. you won't find any sport that has as large a fanbase as soccer almost anywhere in the world. in fact, in recent years the world cup and champions league finales were watched by more people around the globe than the super bowl.

yeah, true, but outside of the US no one gives a shit about NASCAR.
on an international level, formula 1 is really where it's at.
and now guess what nationality the greatest F1 driver of all times is....
